WILLIAM CLIMIE, OF BONESS, SCOTLAND.

GAS-PRODUCER.

Application filed September 13, 1911. Serial No. 649,002.

To all whom it may concern:

Be it known that I, WILLIAM CLIMIE, a subject of the King of Great Britain and Ireland, and a resident bf Boness, Linlithgowshire, Scotland, have invented new and useful Improvements in GasProducers, of which the following is a specification.

This invention has reference to and comprises improvements in' gas producers.

In order that my said invention and the.

manner of carrying same into effect or practice may be properly. understood I have hereunto appended two sheets of explanatory drawings in which Figure l is an elevation partly in section of a gas producer constructed according to my improvements. Figs. 2 and 3 are respectively, an elevation and a plan view of the rake, while Fig. 4 is a plan view of'the' grate. Figs. 5 and 7 are respectively seetional elevations of slightly modified forms of grate, while Figs. 6 and 8 are corresponding plan views.

Referring 'to these drawings :This improved gas producer is composed of an inner casing 1 and an outer casing 2. The

fuel is contained within the inner casing and formed with a space 6 within which toothed rollers 7 are continuously rotated so as to' discharge the ashes and prevent the formation of .clinker. The number of rollers 7 may be varied if desired and as shown by Figs. 1 and 4 are preferably formed hollow so that water maybe passed through them. The water is introduced into the first roller by means of a pipe 44 then passed through the other rollers in sequence by pipes 45 and led from the last roller to a central hollow bar 46 by a pipe 47 and then passed from this bar 46 to a vertical tube 8 by a pipe 11.

If desired and as indicated by dotted lines l9 the top surface of thecbnter bar 46 may be formed of a double incline or inverted V shape in order to assist the movement ofthe ashes toward the rollers 7.

The vertical tube or support 8 is fitted centrally within the casing 1 and continu ously rotated by gearing 9, 10f Water is circulated through this tube in order to'keeD Specification of Letters Patent.

same cool by the pipe 11 as beforementioned HEISSUED and discharged at or near the topby any convenient means. The lower portion of the tube 8 is preferably of hexagonal form in section and a boss 12 formed with projecting arms 13 is mounted on same so as to rotate with the tube 8 but is capable of vertical movement thereon. Bars 14 formed with curved tail pieces or cams 15 are mounted on the arms 13 and a bar 16 formed with teeth 17 on its under surface is fitted to the ends of said bars 14!. It will be readily understood that as'the rake (that is the media-- nism marked 12 to 17) is rotated by the tube 8 the tail pieces or cams 15 cause same to rise through the fuel in a helical manner. Rods 18, fitted to the boss 12 at their lower end, are connected together by'a crosshead 19 at their upper end. One end of a wire rope 20 is connected to this crosshead 19 by a ball bearing joint 21, while the other end is attached to a winch 22 or its equivalent. The rope 20 from the crosshead 19 to the winch I 22 passes over suitable placed guide pulleys 23. The rods 18 pass through the wheel 10 and are rotated with it and where they pass out of the gas producer'e'asing a suitably constructed gas-tight and ball bearing joint 24: is fitted. The winch 22 and rope 20 are for the purpose of raising the rake in order to clean the tube 8 from the the position of the rake in the fuel chamber may be known a suitably constructed indicator 25 may be fitted.

The gas is led from the fuel chamber by a pipe 26 fitted at its upper end to avesscl 27 In order that where the tar and ammonia-compounds are separated from it. Steam is injected into a convenient part of this pipe 26 by an injector or the like 28 so as to scrub the gas, draw it from the gas producer and force it through the separating vessel 27 and condenser 32. Steam is supplied to this injector from the chamber 3 by means of a pipe 30 and valve 31. The gas is led from the separator 27 into another vessel or condenser 32 by means of a pipe An injector 34 placed in a suitable position in this pipe 33 subjects the gas to a second scrubbing action and insures the extraction of any impurities which may have ascended from the chamber 27. The steam is supplied to this injector 3% by a pipe 35 and valveSG from the pipe 30. The purified gases may be drawn off from the condenser by the pipe quired strength they may be spaces .6 between water jackets 48.

29 utilized for various purposes such as heating, driving, or lighting.

The strong ammoniac liquors in the vessel 27 are passed to the condenser 32 by means of a pipe 37 and valve 38 of usual form and from the condenser to a tank 39 by means of a pipe 40. The liquors are then drawn from the tank 39 through a line of piping 41 by means of a pump 42 and delivered into the pipe 26 in the formof a spray in order that the gas from the producer may be washed.

When the liquors have reached the redrawn oil from the tank 39 bythe pipe 43.

As shown by Figs. 5 and 6 the rollers 7 instead of being formed hollow for the passage of water are solid and rotate in the Four rollers are shown in Figs. 5 and 6 while Figs. 7 and 8 illustrate a suitable construction for two rollers.

I claim- *1. The combination in a gas producer of a fuel rake; means for rotating the rake in a constant direction; means for allowing the rake to fall during the said rotary motion;

andmeans operable upon the fuel and moved by thesaid rotating means for effecting-a inovement of the rake upwardly throughthe uel.

2. The combination in a gas producer of a fuel rake; means for moving therake in a constant direction to rake the fuel; means for allowing the rake to fall during the said constant movement; and means moved by said constant moving means to raise the rake upwardly through the fuel.

3. The combination in a gas producer of a fuelrake; means for moving the rake in a constant direction to rake 'f'the fuel; metns for allowing the rake to fall during the said constant movement; and means carried by the said rake and moved b y the said constant moving means to'raise the rake upwardly through the fuel.

4. The combination, in a gas producer, of a fuel rake; means for imparting a rotary movement in a constant direction to the rake, said rake having a cam surface operable against the fuel during the rotary movement of the rake to simultaneously move the rake upwardly through the fuel to rake the latter; and means forlowering the. fuel to effect a downward movement of the rake.

5. The combination of having a casing providing a fuel chamber,
